Great idea for a thread.
A Nuwai QIII flashlight is a great buy. I've seen them for as low as $20, but you'll have to search around.

As a couple of people have pointed out, a Mora carbon steel knife is the ultimate bargain, around $10.

Best deal I ever got was when I asked on BladeForums how I might carry the toolbits for a Leatherman Charge in my pocket (cause I clip it and don't wear the sheath) and someone there sent me a Sabenza leather pouch for free because he thought it would make an excellent holder. Nothing beats good people.

Also, some retailers give discounts to members of CandlePowerForums.com, which another great site you might want to check out. This thread
gives a list of them. In particular, CountyComm is a great place to find bargains, particularly on their secret CPF-only page. (Shhh, don't tell anyone! <img src="/images/graemlins/wink.gif" alt="" />)
